Database tips

🗄️

Export a sample row from your database as JSON and generate a TypeScript interface that matches the record shape — ready to use in your repository layer.

💡

For Prisma, Drizzle, or TypeORM users: generated interfaces can serve as documentation or as a starting point for manually defined model types.

🔢

Database timestamps often come as strings in JSON ("2024-01-15T10:30:00Z"). Generated interfaces use "string" — consider manually changing these to "Date" in your codebase.

🧩

Relational data joined into a nested JSON object (e.g., user.orders[]) generates nested interfaces that mirror your join query structure automatically.
